Probably the best example is feb 14 2007, it has been thrown about lately. Was supposed to be a big ice storm, but we got a nice thump of 2-3inches of snow, then about 3 inches of sleet, then a glaze of ice. It was like a glacier. Happened at night, so not much to see. I was in a big sleet storm in Georgia in the 80’s, poured sleet, pretty miserable to be out in.
